## Conflict Member ID Eligibility Error

`HardEligibilityErrorCode` now includes `CONFLICT_MEMBER_ID`. Hard eligibility in `@usebridge/sdk` and `@usebridge/sdk-react` returns this error when multiple insurance plans match. The error is not retryable and requires a Member ID. See [Hard Check](/documentation/getting-started/eligibility-sdk/hard-check).
